I find that on unisons inside the descernable beat range there is a definant tunable "bloom" like effect.... it matches your description below to a tee. I find also you can get this to show itself in octaves, 5ths, and double octaves. I have been dinking around with this for about a year now both with what Tunelab can show me and help me do... and with my ears... and I have my suspicsions about this "bloom" and our friend with the "natural beat" concept. Tho no doubt a blooming can also result from hammers being voiced just so. > > > The best I can describe bloom is: Strike a note and allow it to sustain.
